NetApp FAS2240-2 with DS4246 Expansion Disk Shelf Design


I recently had the opportunity to design and implement NetApp’s entry-level storage solution for a client and I’d like to take this chance to share my approach to the design decisions. One reason for posting this is to help others that may be contemplating similar designs. I know there are a lot of talented and experienced engineers out there that may come across this and I encourage you to comment on this design. I look forward to learning from your experiences and at the same time I hope mine can help others. I should note that the hardware purchased was outside the scope of this design as the decision had already been made, hardware ordered and shipped. Also, common sense says that I’ve changed hostnames and IP addresses to protect the innocent.

The hardware specifications include

Feature FAS2240-2
Controller Form Factor Single enclosure HA; 2 controllers in a 2U chassis 
Memory 6 GB per controller 
CPU  Dual Core Intel Xeon C3528 @1.73 GHz, HT enabled
